Since I’m using Outlook 2010, I see a lot of GUID references in my Internet Explorer History which makes it hard to use.

For instance;
{6BE240C7-DFC2-4366-8871-08A412F896EB}

When I click on it, I get one of the following;

• a warning which reads;
  "Running a system command on this item might be unsafe"
• a file not found error
• a web page with the text;
  "There are no items to show in this view."

Where exactly is this coming from and how can I make it stop poluting my IE History?
